SHUTTLE CHECKING AND RELEASING MECHANISM FOR LOOMS.

Specification of Letters Patent.

Patented Jan. 21, 1908.

Application filed April 10. 1907. Serial No. 367.389.

' South Bethlehem, in the county of Northampton and State ofPennsylvania, have invented certain new and useful Improvements inShuttle Checking and Releasing Mechanism for Looms, whereof thefollowing is a specification, reference being had to the accompanyingdrawings.

My invention relates in shuttle check binders for looms.

' The object of my invention is to provide means for relieving thestrain on the binder of a shuttle box and removing the pressure fromtheshuttle as it is about to be shot across the raceway on the lay.

In its present embodiment it comprises an arm connected to theprotection rod on the front of the lay, said arm being engaged by apivoted lever and tilted thereby when the lay is in its backwardposition and the shuttle is about to move across the raceway.

It has been found that the shuttle sometimes sticks in its box or ishindered in its start across the raceway, in looms as ordinarilyconstructed; especially is this the case in damp weather. It is,therefore. to overcome this difiiculty that my invention is designed.

In the accompanying drawings, Figure I, is a vertical sectional viewthrough a loom showing my invention applied thereto. Fig.

II, is a front elevation of the shuttle box,

binder mechanism and release.

In said figuresz-the lay 1, is mounted upon swords 2, which are pivotedto the side frames 4. Mounted upon the lay is the shuttle box 6,provided with ,a series of binders 7, which are adapted to retaln theshuttle in the box after it has traversed the raceway in the well knownmanner.

Mounted upon the front of the lay in suitable bearings 10, is theprotection rod 11. At the end of this rod opposite the shuttle box is aprotection finger 12, securely fastened to said protection rod so thatit will be tilted whenever the rod is rotated. About the protection rodis wound a spiral spring 14, which normally tends to keep the protectionfinger 12, pressed against the binder 7. This spring is secured at oneend to the bearing 10, and at the other end to a collar 15, fastened tosaid protection rod. An arm 17, is secured to the protection rod at apoint beyond the collar 15, said arm extending below the lay and beingprovided at its free to an improvement end with a hole to permit freemotion of the pivoted rod 18. through the same. The rod 18, is rotatablymounted upon the rod 20, extending across the loom near the bottom andsaid rod is also provided with an adjustable collar 21, for engaging theunder side of the arm 17. The protection rod is also provided with ashort finger 23, which is adapted to engage the arm 24, on the shipper25, under predetermined conditions.

The lay 1, is oscillated by means of the pitman 28, secured to the crank29, on the shaft 30, which is mounted in bearings 31, upon the sideframes 4.

The operation of the device is as follows When the lay is in theposition shown in Fig. I, the collar 21, of the rod 18, bears againstthe under side of the arm 17 thus oscillating the protection rod 11, andrelieving the binder 7, from the pressure of the finger 12. At this timethe shuttle is shot across the raceway and, as the pressure of theprotection finger against the binder has been released the liability ofthe shuttle to stick in the shuttle box is reduced.

If for any reason the shuttle does not reach the'shuttle box the finger12, presses against the binder 7, during the forward movement of the layand the collar 21, retreats from under the arm 17, thus allowing theprotection rod to turn and move the finger 23, into a position where itwill strike the arm 24, on the shipper 25, and thus stop the loom.

Having thus described my invention, I claim 1. In a loom, thecombination with a lay, shuttle box and binder; of a protection rod onsaid lay; a spring actuated finger upon said protection rod arranged topress against said binder; an arm on said protection rod; a rod pivotedbelow said lay and in slidable relation with said arm; and means on saidrod for engaging said arm to turn said protection rod to relieve thepressure exerted b y said finger upon said binder.

2. In a loom, the combination with a lay, shuttle box and binder; of aprotection rod on said lay; a spring actuated finger upon saidprotection rod to press against said binder; an arm on said protectionrod; a pivoted rod in slidable relation with said arm; and a collar onsaid rod adapted to engage said arm to turn said protection rod torelieve the pressure exerted by said finger upon said binder.

3. In a loom, the combination with a lay,

shuttle box and binder; of a protection rod I relieve the pressureexerted by said finger 10 on said lay; a spring actuated finger uponsaid protection rod arranged to press against said binder; an arm onsaid protection rod extending under said lay; a rod pivotally supportedfrom the loom frame in slidable re lation With said arm; and meansmounted upon said rod below said arm adapted to engage said arm to turnsaid protection rod to upon said binder.

In testimony whereof, I have hereunto signed my name, at Philadelphia,Pennsylvania, this fifth day of April 1907.
